Synthetic cilia-regulated transports through micro and nanofluidic devices guarantee an efficient delivery of drugs and other biological substances. Entropy analysis of cilia stimulated transport of thermally radiated hybrid nanofluid through an electroosmotic pump is conducted in this study. Joint effects of applied Lorentz force and Ohmic heating on the intended stream are also studied. Metachronal arrangements of cilia field coating channel inner side, are liable to generate current in the fluid. After using the lubrication and the Debye-Huckel estimations, numerical solutions of the envisioned problem are obtained. For pressure rise per metachronal wavelength, the pressure gradient is numerically integrated. The analysis reveals that high electric potential results in reducing the heat transfer effects in the flow system. The enhancement of flow is noticed near the channel surface for higher electroosmotic parameters. The irreversibility in the channel decreases when the Helmholtz-Smoluchowski velocity is applied in the opposite direction of the flow and thus produces the fluid friction irreversibility.

通过欧姆加热的电渗泵在热辐射混合纳米流体中产生熵:合成纤毛调节流的情况

通过微米和纳米流体装置的合成纤毛调节的运输保证了药物和其他生物物质的有效输送。本研究对纤毛刺激的热辐射混合纳米流体通过电渗泵的运输进行了熵分析。还研究了施加的洛伦兹力和欧姆加热对预期流的联合影响。纤毛场涂层通道内侧的异时排列,易于在流体中产生电流。使用润滑和 Debye-Huckel 估计后,获得了设想问题的数值解。对于每个异时波长的压力上升,压力梯度是数值积分的。分析表明,高电势会导致流动系统中的传热效应降低。对于较高的电渗参数,在通道表面附近注意到流动的增强。当 Helmholtz-Smoluchowski 速度应用于流动的相反方向时,通道中的不可逆性会降低,从而产生流体摩擦不可逆性。
